Description

FIELD OF THE INVENTION
The invention relates to an oil-gas-water multi-phase flow adjusting apparatus mounted to an oil line of oil field, and a measuring apparatus and a measuring method using the adjusting apparatus and being adapted for measuring oil-gas-water multi-phase flow rate in an oil line of oil field.
DESCRIPTION OF THE PRIOR ART
The changes of each phase production flow rate in oil-gas-water three-phase product in oil wells are the basic data of the oil production of oil field, and are the main basis for monitoring and controlling the dynamic characteristics of oil wells and oil reservoir.
In order to measure mentioned-above data, a conventional method is to deliver the products of many oil wells into a metering separator alternatively, to separate the products of oil wells into three single-phase fluids of oil, gas and water by means of the metering separator, and then to meter them at respective exit respectively. When the metering separator separates the products of oil wells into a gas-liquid two-phase fluid, the total flow rates of gas and liquid are measured respectively, and the productions of the oil and water in the liquid-phase fluid are generally measured by a sample analyses method, a density measuring method or other component measuring methods to obtain the respective proportion of oil and water and then to calculate the flow rates of oil and water.
Since a same separator is used by many oil wells in an oil field, the continuous metering operation can not be realized for a single oil well and the separator has poor separation effects for high production oil wells, so that the metering results have poor representatives and great errors. Secondly, since the structure and the flow process of the oil-gas-water three-phase separator are complex, and the metering separator and its related accessories generally have tens of tons in weight and occupy an area in several hundreds of square meters, to make the maintenance and management of the metering separator system quite complex and miscellaneous and have more links needed to be controlled, so that the costs of establishment, operation and maintenance of the station are high to not facilitate the automatization of the production process and the management to be realized, and such defects are presented more prominently for oil fields in desert and on the sea.
A multiphase flow metering system disclosed in recent years can measure the flow rate of each phase in the oil-gas-water multi-phase flow mixture without necessity for separating oil, gas and water. However, since the oil-gas-water multi-phase flow in the pipe is an extreme complex random process having multi-variables, different flow patterns exhibit under different conditions. Furthermore, in the products of oil wells, the relative contents of the three components of oil, gas and water may change greatly: the products may have high gas content (the gas content is 100%) or be all liquid (the gas content is 0%); in the liquid phase, the liquid may be all oil (the water content is 0%) or have high water content (the water content is more than 95%). And the products may be in any combination of the above extreme values. Accordingly the existing various multiphase flow rate measuring apparatus, no one excepted, can only be adapted to one or a few flow patterns and some flow rate range, and cover a part of combination of gas content and water content. This, to a great extent, limits the extension and use of the multiphase flow rate measurement technology in the production practice.
